I hate my friend's girlfriend

Mys friend thinks that his girlfriend is an angel on earth even though she's unfaithful. She lies to him all the time about where she is, doesn't text or call him ever. She hooked up with another dude at a party and lied about it. He says that he believes her instead of everybody who's said differently. He says that he thinks of her as the center of his galaxy, with school outside of that, and friends and family way on the outer rim. He said that. To a group of his friends. That his new girlfriend is more important than all these lifelong friends and family he's had.

They've only been together a few months. I've expressed to him that I don't think she's a good match for him and he called me a disrespectful c*nt and he's blocked me like 6 different times because he doesn't like that I dislike his girlfriend. She's quite literally all he ever talks about anymore and he doesn't hang out with his other friends or me or anybody else. I'm tired of it. I want my friend back.
